"This is the best phone Samsung as ever made, which isn't a very difficult thing to say given the efforts in the last two years. But it's managed to make a huge leap forward, offering something that's the equal of the best in the market and set a very high bar to reach.

It's still got a couple of niggles: I'd have loved to see a completely redefined TouchWiz, and I'm not convinced the battery life is going to be stellar.

But this phone is simplicity redefined for the South Korean brand. No betting on stupid hand waving gimmicks, no skimping on design to just make it waterproof… this is a premium phone as it should be. Samsung is back."

“Still, thoughtful touches like double-tapping the home button to very quickly launch the camera and auto-tracking autofocus during video seem poised to help dramatically. Throw in support for both major wireless charging standards and magnetic wave payment technology that'll come to the market as Samsung Pay and you've got two devices that seem like the first substantive step forward this lumbering giant has taken in a long time. Is it a huge step? Maybe not, but it's movement in a positive direction.”

"Samsung seems to have listened to what its users want. Battery life and build quality are the two things people have been crying out for improvements in and they're exactly what Samsung has delivered.

In the long run it'll be interesting to see how the all-glass body stands up to drops. But with Cat 6 LTE, wireless fast charging and tap to pay this phone feels future proof. We can't imagine asking for much more from a handset."

"Sleek and powerful, certainly - but it was a fairly bitter presentation. The firm took more than a few snipes at Apple, rather than leaving it to reviewers and users to draw their own conclusions about the Galaxy's many innovations .

The demonstrations of like-for-like pictures and video appeared to put the S6 streets ahead of the iPhone 6, but I imagine Apple would dispute the conditions."

“The design of Samsung's flagship is more refined than ever, although it still doesn't feel quite as premium as the likes of the HTC One M9. It's the Edge that really wins out, with its eyecatching appearance and sleek curves. The Edge's screen technology is still reserved for Samsung's top-tier phones, but the company may well be onto a winning design formula here.”

"Samsung has finally decided that plastic isn't fantastic, with a welcomed move to a full-metal body flagship phone. These waters are already tried and tested routes by the likes of HTC and Apple, where a cheaper looking handset just doesn't cut it anymore in the premium mobile phone world."
